The present disclosure relates to methods and systems for generating data structures. Specifically, the methods and systems relate to data structures for navigational systems of vehicles (e.g., aircraft, boats, cars). For example, data structures can comprise a plurality of locations and data associated with the locations. The locations can be associated with navigation procedures for operating the vehicle. For example, the data structure can provide information for a navigational system of aircraft. The present methods and systems can be used to refine data structures in order to limit the data structures. For example, the present methods and systems can generate and refine search criteria used to create a data structure. The search criteria can be specific to a particular vehicle. For example, the search criteria can be based on the categorization of locations associated with the vehicle. In one aspect, the present methods and systems can be configured to categorize the locations, for a specific vehicle, based on the travel information associated with the vehicle. After a data structure is generated, the storage size of the data structure can be compared to a threshold (e.g., a threshold specific to the vehicle or type of vehicle). If the storage size exceeds the threshold, then the search criteria can be refined and another data structure can be generated based on the refined search criteria. In one aspect, the process of generating data structures can be repeated on a regular cycle.

FIG. 1 is a block diagram illustrating various aspects of an exemplary system 100 in which the present methods and systems can operate. Those skilled in the art will appreciate that the present methods may be used in systems that employ both digital and analog equipment. One skilled in the art will appreciate that provided herein is a functional description and that the respective functions can be performed by software, hardware, or a combination of software and hardware. In an exemplary embodiment, the methods and systems disclosed can be located within one or more first device, second device, and/or vehicle. For example, the methods and systems disclosed can be located in the travel unit, categorization unit, search unit, and analysis unit of the second device.

In one aspect, the system 100 can comprise a first device 102 configured to collect data. For example, the first device 102 can comprise a collection unit 104 configured to collect and store data. In one aspect, the collection unit 104 can be configured to collect data related to a plurality of locations, such as geographic locations. Example locations can comprise ports (e.g., airports, harbors, stations), waypoints, refueling points, and the like. As an illustration, the collection unit 104 can receive data from one or more external data sources. For example, the data can be received from the nation state Aeronautical Information Services. In one aspect, the data can be received in electronic form or paper form. The data can be processed for storage in the collection unit 104. As an illustration, the data can be received as an Aeronautical Information Publication (AIP). In one aspect, the data can comprise airports, procedure, fixes, navigational aids, airways, and/or the like. As a further illustration FIG. 12 shows a diagram of an example data flow. For example, a data service provider 1202 can receive data from a variety of sources 1204, such as notices to airmen (NOTAM), AIPs, Aeronautical Information Service, and other state services. The data service provider 1202 can provide such data to a Flight Management System (FMS) data application integrator 1206 (e.g., first device 102). Then the FMS data application integrator 1206 can provide a data structure for an FMS of a vehicle to an end user 1208, such as a vehicle operator and owner (e.g., at the second device 108). In one aspect, the data can be transferred directly between the parties or through a network 1210.

In one aspect, the first device 102 can comprise a data processing unit 106 configured to generate data structures. For example, the first device 102 can receive requests for data based on search criteria. In response to a request, the first device 102 can generate a data structure, such as a database, comprising data from the collection unit 104. For example, the data processing unit 106 can be configured to select data stored by the collection unit 104 based on the search criteria provided by a requesting user and/or device. In one aspect, a request for data can comprise parameters indicative of a type of data structure and/or format. The data processing unit 106 can be configured to format the results of the search according to the parameters. For example, the parameters can be indicative of a type of data structure, such as a type of database. The parameters can be indicative of a device, such as a vehicle, on which the data structure is intended to be stored. In another aspect, the data processing unit 106 can convert ARINC 424 standard data file to a navigation database file of a flight management system of a vehicle. ARINC Specification 424-20 is herein incorporated by reference in its entirety. Additionally, all prior and subsequent versions to version 20 of ARINC 424 are herein incorporated by reference in their entirety.

In one aspect, the system 100 can comprise a second device 108 configured to manage data for one or more vehicles 110. The second device 108 can comprise a travel unit 112 configured to store and manage travel information. For example, the travel information can comprise travel history for one or more of the vehicles 110. The travel history can comprise a list of locations that the vehicle 110 has traveled to over a time period. As another example, the travel information can comprise travel plans for one or more vehicles 110. The travel plans can comprise a list of locations the vehicle 110 is scheduled to arrive at during a time period. In one aspect, the travel unit 112 can maintain a list of locations for one or more fleets of vehicles. For example, the travel unit 112 can maintain a list of all locations traveled to or scheduled to travel to by any of the vehicles of the fleet. The travel unit 112 can track which vehicles are associated with which locations. The travel unit 112 can also maintain a list of data associated with the locations.

In one aspect, the second device 108 can comprise a categorization unit 114 configured to categorize locations. In one aspect, the categorization unit 114 can receive and/or maintain a list of locations and data associated with the locations. For example, the list of locations and data associated with the locations can be based on travel information collected by the travel unit 112. The categorization unit 114 can be configured to categorize locations for specific vehicles 110. The categorization unit 114 can categorize locations according to categories, such as a first category, second category, third category, fourth category, and the like. The first category can indicate that the location is an intended and/or planned destination of a vehicle. The second category can indicate that a location is an alternate destination for the vehicle. The third category can indicate that a location is a second alternate destination for the vehicle. The fourth category can indicate that a location is an emergency destination for the vehicle.

In one aspect, one or more categories can be associated with a data hierarchy configured to indicate amounts and/or types of data associated with different categories. For example, the first category can be associated with more data and/or more detailed data than the second category, third category, and fourth categories. The second category can be associated with more data and/or more detailed data than the third category and fourth category. The third category can be associated with more data and/or more detailed data than the fourth category. As described in more detail below, FIG. 2 is an example data hierarchy for an aircraft illustrating different categories and the data that can be retrieved for locations associated with each category.

In one aspect, the second device 108 can comprise a search unit 116 configured to request data (e.g., organized as a data structure) from the first device 102. The search unit 116 can be configured to generate search criteria for requesting data from the first device 102. In one aspect, the search criteria can be selected to retrieve data relevant to a specific vehicle. For example, the search criteria can be based on a categorization of locations associated with the vehicle by the categorization unit 114. The request can comprise additional search parameters, such a vehicle information (e.g., vehicle identifier, vehicle type) and data information (e.g., data structure type, data structure size).

In one aspect, the second device 108 can comprise an analysis unit 118 configured to receive and analyze data. For example, the analysis unit 118 can analyze data received from the first device 102 in response to a request from the search unit 116. The analysis unit 118 can be configured to determine the storage size of the data. The analysis unit 118 can be configured to determine a storage capacity of a vehicle associated with the data. The analysis unit 118 can be configured to compare the storage size of the data to the storage capacity of the vehicle. The analysis unit 118 can also compare the storage size to one or more thresholds. The one or more thresholds can be based can on the storage capacity of the vehicle. As an illustration, a first threshold can comprise 90 percent of storage capacity. A second threshold can comprise 95 percent of storage capacity. A third threshold can comprise 100 percent of storage capacity.

If the storage size of the data meets or exceeds one or more thresholds, the analysis unit 118 can be configured to further refine the data. For example, the analysis unit 118 can provide refinement criteria to the search unit 116, and the search unit 116 can request the data again based on the refinement criteria. As another example, the analysis unit 118 can be configured to remove and/or delete portions of the data. In one aspect, such portions of the data can be removed and/or deleted based on the refinement criteria. In another aspect, specific refinement criteria can be associated with one or more thresholds. For example, first refinement criteria can be associated with the first threshold. Second refinement criteria can be associated with the second threshold. Third refinement criteria can be associated with the third threshold. Example refinement criteria are described by FIG. 5 and its associated paragraphs as well as throughout the detailed description.

In one aspect, the analysis unit 118 can be configured to generate one or more reports based on changes in the data structures. For example, the report can be provided to an agent, such as an operator of the vehicle or a dispatcher associated with the vehicle. The report can be provided to an agent as a bulletin, desktop procedure guides, aircraft flight manual (AFM) supplements, and/or the like. As an illustration, the report can comprise operations constraints of an AFM text, a dispatch checklist (e.g., or Re-Route Checklist), an inflight reclassification change from “Q” to “/A” enroute to alternate location, post divert recovery filing outbound considerations (e.g., conventional SID or vector departure), crew procedures for Non-NavDB supported airports, and/or the like.

In one aspect, the system 100 can comprise one or more vehicles 110. A vehicle 110 can comprise a navigation unit 120 configured to assist in navigation of the vehicle 110. For example, the navigation unit 120 can be configured to provide information to an operator (e.g., pilot, captain, driver) of the vehicle. The information can be related to locations relevant to the vehicle. For example, the vehicle 110 can comprise a storage unit 122 configured to receive and store data from first device 102 and/or second device 108. In one aspect, the storage unit 122 can be configured to receive and store data requested by the search unit 116 of the second device 108. For example, the storage unit 122 can store a data structure, such as a database, comprising locations and data associated with locations.

In one aspect, the data structure can be packaged, compiled, or otherwise organized for compatibility with a specific vehicle 110. For example, one vehicle 110 can be associated with a first plurality of locations. Another vehicle 110 can be associated with a second plurality of locations. In some scenarios, some of the locations of the first plurality of locations can be included as locations in the second plurality of locations, and vice versa. In some scenarios, a location of first plurality of locations can be categorized differently than the same location in the second plurality of locations. For example, a location associated with the first category for one vehicle 110 can be associated with the second category, third category, or fourth category for another vehicle 110. For example, different vehicles 110 can be associated with different locations. As another example, one vehicle can be scheduled to visit one location and another vehicle can be scheduled to visit another location. Accordingly, locations can be categorized differently for different vehicles based on current, future, or past travel information. As another example, a data structure can be different for two different vehicles because a storage unit 122 of one vehicle can have different storage requirements (e.g., capacity, format) than a storage unit 122 of another vehicle 110.

In one aspect, the system 100 can comprise a network 124 configured to transfer data to and throughout the system 100. In one aspect, the network 124 can comprise a packet switched network (e.g., internet protocol based network), a non-packet switched network (e.g., quadrature amplitude modulation based network), and/or the like. The network 124 can comprise network adapters, switches, routers, modems, and the like connected through wireless links (e.g., radio frequency, satellite) and/or physical links (e.g., fiber optic cable, coaxial cable, Ethernet cable, or a combination thereof). In one aspect, the network 124 can be configured to provide communication from telephone, cellular, modem, and/or other electronic devices to and throughout the system 100.

As an illustration, the network 124 can transmit requests from the search unit 116 of the second device 108 to the first device 102. The network 124 can transmit the requested data from the first device 102 to the second device 108 and/or one or more vehicles 110. The network 124 can transmit data from the second device 108 to one or more vehicles 110. For example, the second device 108 can be configured to distribute data structures to vehicles 110. In another aspect, the system 100 can comprise one or more data stations 126 configured to receive data for one or more vehicles 110. For example, a data station 126 can be configured to prepare data for delivery to a vehicle 110 through a portable storage device, such as a CD-ROM, flash drive, solid state drive, magnetic disk, memory card, diskette, hard disk, or other storage medium. For example, the portable storage device can be periodically carried by a maintenance worker to the vehicle 110 and uploaded to the vehicle 110.

In one aspect, the present methods and systems can be implemented as part of the management of one or more aircrafts for a fleet of aircrafts. For example, each aircraft can comprise a Flight Management System (FMS) configured to operate with a data structure, such as a Navigational Database (NavDB) that is generated based on the Aeronautical Radio, Incorporated (ARINC) 28 day cycle. The data in the data structure can be used in the operation of the aircraft by providing flight navigation guidance through all phases of flight. This data that is typically stored in the NavDB has been growing in overall size at an annual rate of 8%. Unfortunately, FMS computer (FMC) in aircraft can have limited storage capacity. There has not been a recognized method of organizing NavDB content based on the storage constraints of the NavDB. In one aspect, an optimization process can be designed to first generate a baseline data structure to be included in each aircraft's database, standardize the content, and then remove selected portions of data (e.g., or generate a data structure without the portions of the data) to provide a data structure below the FMC storage capacity and accommodate expected future growth. Such process is illustrated in further detail by the following figures and description.

FIG. 2 is a diagram illustrating an example data hierarchy 200 for an aircraft. In one aspect, the data hierarchy 200 can specify which data is to be retrieved for a location associated with a category. For example, the data hierarchy 200 can comprise a first category 202, second category 204, third category 206, and fourth category 208. In one aspect, the data hierarchy 200 can specify which data is to be received for a variety of data types. Example data types can comprise standard instrument departures (SIDS), standard terminal arrival routes (STARS), instrument approach procedures (TAPS), and airport data. As an example, data can comprise area navigation (RNAV) data, conventional data (e.g., non-RNAV data). Example approach procedures can comprise instrument landing system (ILS) data, localizer (LOC) data, VHF Omnidirectional Range beacon (VOR) data, non-directional beacon (NDB) data, and/or the like. Example airport data can comprise standard airport data, such as data, procedures, and the like derived from a Nation State Aeronautical Information Publication (AIP) without any modification or addition to the data. For example, the standard data can comprise data provided from an Aeronautical Information Publication (AIP). As an illustration, standard data can comprise AIP published data converted, without modification (e.g. other than format) or addition of data, into an ARINC 424 standard file by a Type 1 LOA holding Data Service Provider. Such Data Service Suppliers and avionics manufacturers can comply with FAA guidelines for the acceptance of data suppliers & avionics manufacturers as DO-200A compliant with respect to Navigation Databases. In contrast, data that is modified is no longer standard data but custom or tailored data. As a further illustration, FIG. 13 shows data flow for an example vehicle operator.

In one aspect, the first category 202 can be associated with locations that are destinations of a vehicle (e.g., aircraft). A destination can comprise a location that a particular vehicle goes for revenue freight service, a scheduled destination, and/or the like. In one aspect, the data hierarchy 200 can specify that all available procedures be made available for locations associated with the first category 202. For example, (RNAV SIDS, STARS and ALL APPROACHES). In one aspect, the first category 202 can have the highest level of services (e.g., approaches) available, and consequentially requires more storage space.

In one aspect, the second category 204 can be associated with locations that are alternate destinations of a vehicle (e.g., aircraft). For example, an alternate destination can comprise an airport that is, or may be used on a flight plan route (FPR) as an alternate (ALTN) for a given destination (DEST). This second category 204 can specify the same data as the first category, except without RNAV SIDS or CONVENTIONAL STARS. Eliminating this data saves considerable storage space. If a conventional STAR becomes assigned inbound to a specific airport, the crew can build the conventional STAR in the FMC from the Chart without filing code degradation or consequence. When traveling outbound, the aircraft can be filed on a conventional SID.

In one aspect, the third category 206 can be associated with locations that are diverted destinations of a vehicle (e.g., aircraft). A diverted destination can comprise a demoted alternate destination, or a promoted emergency destination. Locations associated with the third category 206 can be airports that have particularly challenging qualities (e.g. no conventional IAPS) that support inclusion of only RNAV Instrument Approaches and airport data. In one aspect, locations associated with the third category can with SIDs, STARS or CONVENTIONAL TAPs. In some scenarios, there can be advanced option technique to add ILS/LOC and RNAV STARS depending on memory utilization.

In one aspect, the fourth category 208 can be associated with locations that are emergency destinations of an aircraft. An emergency destination can comprise a good airfield but not a freight destination, or an alternate, that is still suitable or expected for city pairs and/or along route of flight. Locations associated with fourth category can only be provided with standard Airport Data. For example, such locations can be without SIDS, STARS or IAPs. For example, locations associated with the fourth category can have data for all runway (RWY) and airport definition data, and any associated Navaid frequencies associated with the location.

FIG. 3 is a diagram illustrating an example process 300 for generating and refining data structures for a vehicle. In one aspect, an oversized data structure can be generated. For example, the oversized data structure can exceed an oversize threshold. In response, the oversized data structure can be replaced with a new data structure (e.g., Alpha NavDB). The new data structure can be based on search criteria configured to limit the data structure below a threshold. The data structure can be regenerated immediately or after an extended period of time (e.g., in cycles of 28 days). It is contemplated that the overall data from which the data structure is generated can grow over time (e.g., as illustrated 8 percent growth). As the overall data grows, the same search criteria can result in subsequent data structures that are larger in size than previous data structures generated with the same search criteria. Thus, the search criteria can be further refined in response the subsequent data structures reaching size thresholds.

In one aspect, the process 300 can begin with a clean slate phase. In the clean slate phase, the process 300 can begin by erasing the existing data structure (e.g., NavDB) of a vehicle so that the data structure contains no specialized contents. In some implementations, the contents of the data structure can be saved in another location before erasing the data structure. The deleted contents of the data structure can then be reviewed and compared to a subsequent data structure that is generated. For example, the old data structure and the new data structure can be compared to see what data has been eliminated. As an example, airports, company routes, custom procedures, non-compulsory waypoints, National Reference Points, or guided VFR procedures can be removed from the data structure after the data structure is erased. Additionally, any other unnecessary and/or unauthorized Data (ARINC Field selectable) can be removed. As a result of erasing the data structure, the waypoint count in the data structure can be reduced to zero.

After the clean slate phase, the process 300 can proceed to a prospecting phase. During the prospecting phase, locations can be discovered and qualified. For example, a search can be performed to identify all known locations that a vehicle might visit, such as revenue destinations currently being planned and flown. The result of the search can be a list of airports that the vehicle flies to that is fleet specific. For example, the locations can be selected from a list of locations maintained by the travel unit 112 of FIG. 1 . In one aspect, the list generated during the prospecting phase can be based on generic understanding of what a filed destination, filed alternate, or a convenient emergency aerodrome. In one aspect, the prospecting phase may require processing of data, such as operations Fly Out Scheduling products, Charter Operations, GOC city/alternate automation and past Flight Plan releases. In another aspect, the list generated in the prospecting phase can be based on third party information for locations associated with maintenance operations, depot operations, flight testing, futures planning, and/or painting. In one aspect, the prospecting phase can be completed without considering categorization of locations and can be accomplished without referencing or addressing a divert category.

FIG. 4 is a diagram illustrating an example data hierarchy for generating a data structure. In one aspect, the data structure can be referred to as an alpha data structure. The data structure can comprise a first compilation of data based on locations associated with the first category, second category and fourth category. In one aspect, search criteria can be generated based on these categories. The search criteria can be sent to a data provider for production of a fully operational data structure (e.g., NavDB). The data structure can be used operationally with one or more vehicles. In one aspect, the search criteria can be based on specific instruction sets exchanged with the data provider to manipulate the search criteria such that the search criteria obtains the data specified by the data hierarchy. For example, the search criteria can be based on ARINC discriminators that filter the available procedures included in the data structure. In one aspect, the search criteria can be selected such that a first threshold is met. For example, the first threshold can be set at 85 percent maximum capacity of a storage device. In one aspect, the search criteria can be based on a location limitation (e.g. waypoint FMC constraint limit). If a first attempt to generate the first data structure does not achieve between 85 to 90 percent max capacity, then a redaction technique(s) can be used.

In one aspect, the search criteria can be based on boolean criteria provided by the data provider. For example, in addition to search criteria related to the categorization of locations, the search criteria can be related and/or based on: area of operation (AOR) definition (e.g., theater of operations), region selection, default criteria (e.g., options), condition (e.g., less than 7000 foot runway, Victor Airways), filters, GEO areas, Multiple GEO areas, specialized data (e.g., HAR, Orphan T and Q Routes, Non-Compulsory, Enroute Holding).

As a further explanation, the search criteria can comprise rules provided to a FMS data integrator. In one aspect, the rules can comprise waypoint selection rules. The waypoint selection rules can be selected ON or OFF. When selected ON, waypoints can be filtered based on the category of the waypoint coded by ARINC 424 waypoint types. Example categories can comprise: waypoints referenced by STARS, Visual Reporting Points, Unnamed uncharted intersections, Special Use Airspace and Off-Route intersection points, waypoints referenced by SIDs, Instrument Approaches, Pitch and Catch points, grid waypoints, waypoints referenced by multiple, floaters, Latitude and Longitude with all zeroes in minutes and seconds, all waypoints not already included via other rules, and/or the like.

In one aspect, the search criteria can be based on a custom list of standard waypoints. For example, a group of points can be entirely excluded based on a search criterion or rule. If certain waypoints from this group of waypoints are identified as operationally important in day to day operations of a vehicle, then such waypoint can be specified on the custom list for inclusion in the data. In one aspect, the search criteria can be based on rules that limit the types of airways. For example, the search criteria can include or exclude Victor (e.g., low) Jet, Tacan, or GPS supported RNP types called T and Q routes. For example, a rule can define a distance from a location (e.g., airfield). A rule can specify certain types of airways based on whether the airway is within the defined distance. In one aspect, the search criteria can request locations with a runway that is less than or more than a specified runway length. In one aspect, the search criteria can specify (e.g., for inclusion or exclusion) data associated a set of countries by referring to region/Area or by Country Codes (e.g., ICAO codes). As a further example, FIG. 14A and FIG. 14B are diagrams illustrating example ICAO codes. FIG. 14C is a diagram showing example region/areas that can be specified by the search criteria.

In one aspect, the search criteria can specify any combination of Approaches, SIDS, STARs for specific locations (e.g., airports), as well as the ability to limit approach types at specific locations. In one aspect, the search criteria can comprise a rule to remove a particular type of instrument approach, such as all NDBs, or RNAV (RNP)'s, or both, or any other combination. The search criteria can also comprise rules to turn off duplicate types of instrument approaches to the same runway (RWY). For example, if there are four RNAV (GPS) approaches, the search criteria can specify inclusion of only the primary approach.

In one aspect, the search criteria can specify geometric areas (e.g., polygons on the earth surface), and rules and exceptions (e.g., as described herein) can be applied to such areas. The search criteria can define Theater or Area of Operation (AOR).

In another aspect, search criteria can be further defined for each geometric area defined by a shape such as polygon. These search criteria can be applied, or nested to include or exclude as necessary to pair the data to a manageable size. For example, smaller geographic areas can be defined within larger geographic areas. As a further illustration, FIG. 15A is a diagram showing example geographic areas. FIG. 15B is a diagram showing example geographic areas that overlap with other geographic areas.

In one aspect, during the generation of the data structure search criteria related to the third category can be omitted. This option allows for the data structure to function as baseline for future generation of data structures. For example, as illustrated in FIG. 6 , during a future generation of data structure, some locations can be modified such that they become associated with the third category. As an example, locations can be demoted from the second category and/or promoted from the fourth category to the third category.

In one aspect, the data structure can consist of relevant locations, such as airports, but further adjustment can be applied to the data structure and/or search criteria such that the data structure comprises only data necessary to operations as specified in the data hierarchy. For example, in order to prevent of data structures from being above storage limits, several thresholds can be used to evaluate the data structure. For example thresholds can be pre-defined at 90 percent and 95 percent of total storage capacity of a vehicle. In one aspect, one or more thresholds can have a prescribed set of structured actions to reduce the next cycle's contents to remain below the storage capacity.

In one aspect, a data structure can be oversized when the data structure exceeds the storage capacity of the vehicle for which the data structure is intended. Oversize conditions can be responded to with immediate, pre-planned and briefed steps with associated consequences. For example, if a data structure is oversized, it can be important to quickly respond to the data provider with refined search criteria in order to generate a smaller data structure. After the data structure is trimmed to an undersized quantity, the data structure can be produce and distributed. Additionally, management can be notified of the preplanned operational consequence. In one aspect, a variety of search criteria can be suggested in order reduce the size of the data structure. The search criteria can be based on the following policies. These suggested search criteria can be approved and provided to the data provider.

In one aspect, the search criteria can be refined to produce a smaller data structure as follows. The search criteria can specify that waypoints that are referenced (e.g., Referenced Only waypoint) can be selected for procedures and airways. Such criteria can remove all non-essential waypoints not included in a procedure. In one aspect, the search criteria can be refined incrementally over several build cycle of the data structure. For example, all non-reference waypoints can be included in the 75 NM circle around each location (e.g., airport), some locations or only the destination locations—or all at once. The search criteria can specify that only one JAP type per RWY end be included in the data structure. Such criteria can remove duplicate or multiple versions of IAP and all associated extra waypoints. The search criteria can specify that Victor Airways can be removed that are outside of 75 NM of the airport list. Such criteria allows for removal of commonly unnecessary points.

In one aspect, if the greater storage capacity is desired, an additional storage device can be activated, such as Gemini. Gemini can be a soft memory expansion that is not available on all aircraft and comes with monthly fee. Use of Gemini can comprise hiding data and procedures in Custom files that may warrant need for additional crew training. Because of this complication, use of Gemini should be the last resort.

In one aspect, when a data structure is greater than 95 percent of the storage capacity (e.g., but not oversized), the following policies can guide refinement: consider and/or redefine area or theater of operations (AOR) definition associated with a vehicle, verify that the locations continue to be categorized correctly and remove any unnecessary locations, adjust or make inclusive GEO Areas, remove required navigation performance authorization required procedures (RNP) (AR), restrict the second category locations to only RNAV (GPS) IAPs and RNAV STARS, and/or the like.

As a further explanation, when a data structure (e.g., NavDB) has exceeded 95% of a limiting resource capacity (e.g., Memory Space, Procedure Count, Airport Count, Waypoint Count) but still under 100% the data structure is still considered “undersize.” The data structure is close to exceeding storage capacity (e.g., oversize in the near future, maybe next cycle). In some scenarios, the threshold value of 95% can be a good threshold at which to redefine the conditions and utility of the current contents and function of this data structure. Thus, validation and/or re-validation of the locations and associated categories (e.g., Destinations, Alternates and Emergency Airfields) can be performed. If the size of the data structure is not reduced enough by manipulation of the search criteria, then geometric areas (e.g., polygons on the earth surface) can be made with rules and exceptions applied within the areas. This action can define, at least in part, a finite Theater or Area of Operation (AOR). The area of operations can be associated with one or more vehicles. An AOR is generally less than the whole world and can provide geometric boundaries associated with activity (e.g., travel plan, travel history) of a vehicle.

In one aspect, when a data structure is greater than 90 percent of the storage capacity (e.g., but less than 95 percent), the following policies can guide refinement: remove High Altitude Reference Waypoints (e.g., suggest partial remove first criteria, such as all except East of KIND), remove ALL RVFPs (FMS VISUALs procedures), remove routes not referencing ground based navigational aids such as T and Q routes (e.g., suggest only a partial removal first), remove Country Codes/region selection (e.g., suggest removal of AFRICA), verify that the locations are categorized properly (e.g., destination, alternative, divert, emergency) and remove all unnecessary data, adjust or make inclusive geographic (GEO) Areas (e.g., country codes and ICAO codes), and/or the like. As previously explained, FIG. 14A-FIG. 14C and FIG. 15A-FIG. 15B are diagrams illustrating example geographic areas.

As a further explanation, when a data structure is greater than 90% storage capacity of a vehicle but still less than 95%, some mild modification to the data structure can be performed (e.g., by generating a new data structure or editing a data structure. As an example, High Altitude Reference Waypoints (HARS) are a set of waypoints, also called Navigational Reference System (NRS), that the FAA has created to create a grid across the country for high-altitude, RNAV-equipped aircraft. In one aspect, HARS/NRS waypoints that are never or rarely used (e.g., or used less than a threshold amount) can be removed from the data structure (e.g., by search criteria). For example, a location can be associated with HARS waypoints on both the west side and east side of the location. As a further example, HARS waypoints on the East side of the location can be removed from the data structure but HARS waypoints on the West of the location can remain in the data structure. As another example, any procedures that are restricted from actual Instrument Meteorological Conditions (IMC) can be removed. Such procedures can comprise RNAV VISUAL FLIGHT PROCEDURES (RVFPs) and FMS Visuals. Operationally, these procedures can be substituted by Radar Vectors to final or an actual IMC capable procedure in the FMS. As another example, T and Q routes can be removed. For example, T and Q routes are RNAV based routes across the country that do not reference any ground based Navaids. T and Q routes can be so numerous that they can be substituted with other options. For example, T and Q routes can be substituted for all Jet Routes and a small combination of HARS waypoints in an include list may suffice.

As a further illustration, example search criteria for an airplane can be as shown in Table 1, Table 2, and/or Table 3. For example, default search criteria can be defined as shown in Table 1. As another example, search criteria can be defined for a variety of groups, such as by geographic area, by area code, and/or the like as shown in Table 1. Search criteria can be defined by airport group as shown in Table 1 and Table 2. In one aspect, airport groups can be defined based on the category (e.g., destination, alternate, divert, emergency) associated with an airport as shown in Table 1 and Table 2. For example, search criteria can be organized by airport groups. As another example, selection criteria can comprise a list of waypoints, airways, and/or the like as shown in Table 3. For example, the criteria can specify specific information to include and/or exclude for certain criteria. For example, all procedures, no procedures, and/or the like for a given criteria can be specified. For specific categories (e.g., default, geographic area, airport group, ICAO code), rules can be selected for corresponding record types, such as AIRPORT, AIRPORT NDB, AIRPORT WAYPOINT, RUNWAY, ENROUTE NAVAID, LOCALIZER, ENROUTE NBD, ENROUTE WAYPOINT, ENROUTE AIRWAY, APPROACH, SIDS, STARS, and/or the like.

FIG. 5 is a flowchart illustrating a process 500 for reviewing and refining a data structure. At step 502, a list of locations (e.g., airports) can be received. For example, a data structure can be generated. The data structure can be a database, data store, list, and/or the like. The locations can comprise ports (e.g., airports, harbors, stations), waypoints (e.g., points on a navigation route), refueling points, and/or the like.

At step 504, custom procedures associated with the locations can be reviewed and removed from the data structure. In one aspect, a review of the procedures associated with all these airports can be performed. Customized procedures can be assessed to determine the applicability, currency, and/or redundancy of the customized procedures. In one aspect, customized procedures can be removed and replaced with standard data. For example, RNAV visual flight procedures (RVFPs) associated with locations can be removed, especially if the RVFPs are associated with a location that is not associated with the first category. Other removals of data from the data structure can be performed on a gradual basis over successive data structure generation cycles. As the data is removed during each generation of the successive data structure, the impact on operation and management of the vehicle can be assessed.

At step 506, custom waypoints can be reviewed and removed. In one aspect, removal of custom waypoints can be performed on a gradual basis during several cycles of generating data structures. For example, custom waypoints can be ranked according to priority of keeping the custom waypoints in the data structure. The lowest priority custom waypoints can be removed before higher priority custom waypoints. As a further example, custom waypoints that are further from a navigational path and/or destination can be removed. Custom waypoints that are associated with alternate and/or emergency destinations can be removed. The custom waypoints can be removed gradually as a predefined amount of time or data structure build cycles pass since the custom waypoint was last relevant to (e.g., used in) the travel of the vehicle (e.g., airplane).

At step 508, waypoints can be selected for inclusion and/or exclusion from the data. Waypoints can be selected based on search criteria. For example, waypoints can be excluded and/or included based on search criteria. In one aspect, waypoints can be included if the waypoint is included on an include list. For example, terminal waypoints can be selected. Terminal waypoints can be waypoints that are coded as related to a location, but not necessarily associated with a procedure. As a further example, terminal waypoints can comprise enroute waypoints and noncompulsory reporting points. In one aspect, procedure referenced waypoints can be selected. Procedure reference waypoints can be a subset of the terminal and enroute waypoints. Procedure referenced waypoints can comprise waypoints that are part of a named procedure. In another aspect, step down waypoints can be reviewed and removed. For example, a step down waypoint (e.g., step down fix) can be a named fix after a final approach fix (FAF). Step down waypoints may depend on FMC design. For example, some FMC may exclude step down waypoints (e.g., due to safety concerns). As an example, step down waypoints may not be included at all inside the final approach fix (FAF) but may allow FAF back to the Initial approach fix (IAF). As a further illustration, FIG. 16A is a diagram showing a vertical profile of an instrument approach with no step down fixes (e.g., step down waypoints). FIG. 16B is a diagram showing a vertical profile of an instrument approach with step down fixes (e.g. step down waypoints).

In a further aspect, orphaned waypoints can be selected. Orphaned waypoints can comprise waypoints that are not compulsory reporting points or can be referenced points derived from operational reports. These points can comprise an include list. Should a report of a needed waypoint be garnered from Dispatch or an Ops Report, consideration for inclusion into an Orphaned waypoint list can be recommended. By way of further explanation, some waypoints can be excluded from the data based on the search criteria. In some scenarios, a portion of the excluded waypoints may be later desired for inclusion in the data. For example, orphaned waypoints are waypoints previously excluded that were later found to be desired for inclusion in the data due to operational necessity. These orphaned waypoints can be added to a special list for inclusion (e.g., during each cycle in compiling a data structure). In one aspect, orphaned waypoints can be added based on an in-service report from a crew or dispatch. For example, a country (e.g., China) might label a waypoint as a significant terminal waypoint without associating the waypoint with any named procedure. Such waypoint may be excluded from a data structure of a vehicle based on the search criteria. Such exclusion may not be desirable because if a waypoint tends to be used by Air Traffic Control. Additionally, flight clearances may be commonly used with these waypoints. Thus, it can be desirable to include such waypoint on the orphaned waypoint list (e.g., include list). Data for such waypoint can be included in a data structure based on the orphaned waypoint list.

FIG. 6 is a diagram illustrating a data hierarchy for generating another data structure. After first obtaining a valid data structure (e.g., when the data structure is below an oversize threshold) analysis of remaining storage of a vehicle allows for additional features to be added and advanced techniques applied to optimize the contents of the subsequent data structures. For example, some locations associated with various categories can be associated with a different category. For example, a location associated with the second category can be associated with the third category instead of the second category. As another example, a location associated with the fourth category can be associated with the third category instead of the fourth category. Depending on how much storage remains below a threshold additional features may be added to the search criteria sent to the data provider. For example, the search criteria can be modified to select one or more HAR waypoints, FMS visuals, custom routes, and/or orphaned waypoints.

In one aspect, any upgrading of additional locations or special features added can be documented as post-baseline addendums. Accurate documentation not only keeps a record of validated contents but also enhances redaction options when active management thresholds are exceeded (e.g. 95%, 90% total capacity). In one aspect, managing the data structure contents can be a monthly event in line with the ARINC cycle. As subsequent data structures are generated, the following criteria can used: data structures should be near 90-95 percent (e.g., or lower) of storage capacity of the vehicle, custom data procedures can be avoided (e.g., deleted, purged), standard data can be prioritized over other data, and IAPs can be prioritized for inclusion over VGFP.

FIG. 7 is a flowchart illustrating a process 700 for adding ad hoc locations to a data structure. In some scenarios, a vehicle can be associated with a location on an ad hoc basis. For example, a vehicle can have a regular travel plan with routine destinations. An ad hoc location is a location that is added to the travel plan but may not be expected to be a location to which the vehicle travels in the future. If the ad hoc location is not currently in the data structure associated with a vehicle or location list used to select data structures, such location can be added to the data structure. Once the ad hoc location is categorized as a destination (e.g., first category or other category), then the ad hoc location and related data can be included in the data structure associated with a vehicle as long as the ad hoc location continues to be requested to be associated with the vehicle. If no longer requested, the location and its associated data can gradually be removed from the data structure. For example, if the location is not requested during a specified number of cycles (e.g., two cycles), the location can be removed. As shown in FIG. 7 , if the location is revalidated (e.g., requested), the location can continue to be categorized under the first category during the next cycle of data generation. If the location is not revalidated, the ad hoc location can be categorized under another category (e.g., lower priority category), such as the third category.

In an aspect, the ad hoc location can be categorized under the first category during the first cycle 702. If the ad hoc location is not requested for the second cycle, then the ad hoc location can be categorized under the second location during the second cycle 704. If the ad hoc location is requested again for the second cycle, the ad hoc location can be categorized under the first category 702. If the ad hoc location is not requested for the third cycle, the ad hoc location can be categorized under the third category 706. If the ad hoc location is requested again after the third cycle, then the ad hoc location can be categorized again under the first category 702. If the ad hoc location continues to not be validated or requested after the third data cycle, then the ad hoc location and its associated data can be completely removed from the data in future data structure generation events, such as during a fourth cycle 704.

FIG. 8 is a flowchart illustrating an example method 800 for optimizing data. At step 802, locations can be categorized, based on travel information associated with a vehicle, according to at least one of a first category and a second category. For example, the first category can indicate planned destinations of the vehicle. The second category can indicate alternate destinations of the vehicle. In one aspect, the travel information can comprise at least one of a travel plan and a travel history of the vehicle. In another aspect, categorizing, based on travel information associated with the vehicle, locations according to at least one of a first category and a second category can further comprise categorizing locations according to a third category, fourth category, and/or additional categories.

At step 804, search criteria can be generated based on the categorization of the locations. For example, the search criteria can be configured to select first data for locations categorized with the first category and second data for locations categorized with the second category. In one aspect, the first data can be more detailed than the second data. For example, the first category can specify that certain data requested that is not specified by the second category.

At step 806, information based on the search criteria can be received. For example, the information can comprise a data structure, such as a database configured for a navigation system of the vehicle. The data structure can comprise first data for locations associated with the first category and second data for locations associated with the second category.

At step 808, a storage size of the information can be determined. For example, the storage size can determined based on the amount of hard disk space the information uses when stored on an intermediate device. For example, the data structure may be compressed and/or converted to another format when stored on the device. Accordingly, the storage size for the compressed and/or converted file can be determined.

At step 810, the storage size can be compared to a threshold. In one aspect, the threshold can be a threshold specific to the vehicle. For example, the threshold can be 85, 90, 95, or 100 percent of the storage space of a device, such as a navigation system of the vehicle. At step 812, the search criteria can be refined if the storage size is above the threshold. For example, new search criteria can be determined. In one aspect, the new search criteria can specify that certain types of data be excluded. For example, certain types of data can be excluded from one or more of the categories.

At step 814, the information can be updated based on the refined search criteria. For example, a new data structure can be generated based on the refined data structure, and the new data structure can comprise an updated version of the first data and second data. The new data structure can comprise more or less information, different information, and/or the like from the data structure.

At step 816, the information can be provided to the vehicle. In one aspect, providing the information to the vehicle can comprise uploading the information to a navigational database of a vehicle. For example, the vehicle can comprise an aircraft. For example, the information can be converted to a navigational database file. The information can be uploaded via a network connection, USB stick, direct connection, diskette, and/or the like.

At step 818, a report can be generated based on changes from previous information to the information. The report can be generated at the vehicle, at a station and provided to the vehicle, and/or the like. For example, the report can indicate changes in duties for an agent associated with the vehicle. For example, the agent can be at least one of a pilot associated with the vehicle and a dispatcher associated with the vehicle.

FIG. 9 is a flowchart illustrating another example method 900 for optimizing data. At step 902, search criteria (e.g., search criteria shown in Table 1, Table 2, and/or Table 3 or otherwise described herein) can be received. In one aspect, the search criteria can be configured to select first data for locations associated with a first category and second data for locations associated with a second category. In one aspect, the first data can be more detailed than the second data. In another aspect, the first locations can associated with the first category based on travel information of the vehicle. The second locations can be associated with the second category based on the travel information of the vehicle. In one aspect, the search criteria can be further configured to select third data for locations associated with a third category, fourth category, or other categories. The third category can indicate emergency destinations of the vehicle. In one aspect, the travel information can comprises at least one of a travel plan and a travel history of the vehicle. As an illustration, the first category can indicate planned destinations of the vehicle and the second category can indicate alternate destinations of the vehicle. In one aspect, the vehicle can comprise an aircraft.

At step 904, a data structure can be generated based on the search criteria. In one aspect, generating the data structure based on the search criteria comprises generating the data structure in a format suitable for a navigational system and associated navigation database of the vehicle. For example, the data structure can be formatted for an electronic flight bag, flight navigational system, and/or the like. The data structure can be formatted according to parameters. For example, the parameters can be indicative of a type of data structure, such as a type of database. The parameters can be indicative of a device, such as a vehicle, on which the data structure is intended to be stored. In another aspect, the data structure can be converted from an ARINC 424 standard data file to a navigation database file of a flight management system of a vehicle.

At step 906, a storage size of the data structure can be determined. For example, the storage size can determined based on the amount of hard disk space the information uses when stored on a device. For example, the hard disk can be analyzed to determine capacity of the hard disk, space used by the data structure, and/or the like. For example, the data structure may be compressed and/or converted to another format when stored on the device. Accordingly, the storage size for the compressed and/or converted file can be determined.

At step 908, the storage size can be compared to a threshold. In one aspect, the threshold can be a threshold specific to the vehicle. For example, the threshold can be 85, 90, 95, or 100 percent of the storage space of a device, such as a navigation system of the vehicle. Additionally, the storage size can be compared to multiple thresholds. The thresholds can be associated with vary levels of notifications, warnings, corrective procedures, and/or the like.

At step 910, a notice that the storage size is above the threshold can be provided. For example, the notice can be provided to a management device used to manage a fleet of vehicles. The notice can be provided as a message (e.g., pop-up message), electronic notification, email, audible alert, and/or the like. For example, the notice can be transmitted across a network.

At step 912, refined search criteria can be received if the storage size is above the threshold. For example, new search criteria can be received (e.g., search criteria shown in Table 1, Table 2, and/or Table 3 or otherwise described herein). The new search criteria can be received from a user. In one aspect, the new search criteria can specify that certain types of data be excluded. For example, certain types of data can be excluded from one or more of the categories. For example, waypoints, procedures, locations, and/or the like for certain categories can be excluded.

At step 914, the data structure can be updated based on the refined search criteria. For example, a new data structure can be generated based on the refined data structure, and the new data structure can comprise an updated version of the data structure. The new data structure can comprise more or less information, different information, and/or the like from the data structure.

At step 916, a report can be generated based on changes from a previous data structure to the data structure. The report can be generated at the vehicle, at a station and provided to the vehicle, and/or the like. In one aspect, the report can indicate changes in duties for an agent associated with the vehicle. For example, the agent can be at least one of a pilot associated with the vehicle and a dispatcher associated with the vehicle.

At step 918, access can be provided to the data structure. In one aspect, providing access to the data structure can comprise providing a server comprising the data structure. For example, the server can comprise a file transfer protocol server. The data structure can be downloaded from the service and uploaded on to the hard disk of the vehicle.

FIG. 10 is a flowchart illustrating yet another example method 1000 for optimizing data. At step 1002, a first data structure associated with a vehicle can be received. The first data structure can be received from the vehicle, a device configured to generate the first data structure, and/or the like. In one aspect, the vehicle can comprise an aircraft, boat, car, and/or the like. For example, the first data structure can be a data structure configured to assist a navigational system of the vehicle. For example, the data structure can be a navigational database file.

At step 1004, the storage size of the first data structure can be determined. For example, the storage size can determined based on the amount of hard disk space the information uses when stored on a device. For example, the data structure may be compressed and/or converted to another format when stored on the device. Accordingly, the storage size for the compressed and/or converted file can be determined.

At step 1006, the storage size of the first data structure can be compared to a threshold. In one aspect, the threshold can be a threshold specific to the vehicle. For example, the threshold can be 85, 90, 95, or 100 percent of the storage space of a device, such as a navigation system of the vehicle. Additionally, the storage size can be compared to multiple thresholds. The thresholds can be associated with varying levels of notifications, warnings, corrective procedures, and/or the like.

At step 1008, search criteria can be identified based on travel information of the vehicle. In one aspect, the travel information can comprise at least one of a travel plan and a travel history of the vehicle. The search criteria can also be identified based on the comparison to the threshold. In one aspect, identifying search criteria based on the travel information of the vehicle and the comparison to the threshold can comprise categorizing, based on the travel information associated with the vehicle, first locations according to at least one of a first category and a second category. The first category can indicate planned destinations of the vehicle. The second category can indicate alternate destinations of the vehicle. In another aspect, identifying search criteria based on the travel information of the vehicle and the comparison to the threshold further can comprise categorizing second locations according to a third category, fourth category, or other category. The third category can indicate emergency destinations of the vehicle.

At step 1010, a second data structure associated with the vehicle can be requested based on the search criteria. For example, the second data structure can be requested from a data supplier. The second data structure can comprise locations selected from a database of locations. The second data structure can comprise data associated with the selected locations. For example, the second data structure can comprise procedures (e.g., flight procedures), waypoints, locations, navigational paths, and/or the like.

At step 1012, the second data structure can be provided to the vehicle. In one aspect, providing the second data structure to the vehicle can comprise uploading the second data structure to a navigational database of a vehicle. For example, the second data structure can be converted to a navigational database file. The second data structure can be uploaded via a network connection, USB stick, direct connection, diskette, and/or the like.

At step 1014, a report can be generated. The report can be generated at the vehicle, at a station and provided to the vehicle, and/or the like. For example, the report can be generated based on changes from the first data structure to the second data structure. The report can indicate changes in duties for an agent associated with the vehicle. The example, the agent can be at least one of a pilot associated with the vehicle and a dispatcher associated with the vehicle.

In an exemplary aspect, the methods and systems can be implemented on a computer 1101 as illustrated in FIG. 11 and described below. By way of example, the first device 102, second device 108, data station 126, and vehicles 110 of FIG. 1 can each be a computer as illustrated in FIG. 11 . Similarly, the methods and systems disclosed can utilize one or more computers to perform one or more functions in one or more locations. FIG. 11 is a block diagram illustrating an exemplary operating environment for performing the disclosed methods.

The disclosed methods can also be practiced in grid-based and distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote computer storage media including memory storage devices.

Further, one skilled in the art will appreciate that the systems and methods disclosed herein can be implemented via a general-purpose computing device in the form of a computer 1101. The components of the computer 1101 can comprise, but are not limited to, one or more processors or processing units 1103, a system memory 1112, and a system bus 1113 that couples various system components including the processor 1103 to the system memory 1112.
